Specification forming part of Letters Patent No. 158,743, dated January l, 1875;-application filed November 28, 1874.

' To all'whom it may concern:

Be it known that I, SAMUEL R. SCHARF,

of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Machine for Cleaning Privy-Vaults and like places; and I do hereby declare that the following is a full and exact description of y ,A the 'sam'e reference being had to the aecompanying rawings, and t0 the letters of reference marked thereon.

The objectQf :my invention isf animprovement in machines for .cleaningcprivy-vaults and like places in a--moreconve1iientexpe d-itious, audvneat manner, avoiding the noi some stench consequent upon such cleaning;

I and my invention herein consists principally in .thexiprnbll,?.J,1,ifb1 ..cIlthe` receiringsel "an air-pump and the connections inl a particulark manner; in the means used for deodorizing; and in the combination and-arrangement of the deodorizer in connection with the other principal operative parts, al as more fully hereinafter described.

- .In the drawings, Figure lis an elevation of `pivoted in a standard, C.A .Upon the body A may be placed a sufficient number of proper tanks, vessels, or receptacles, a convenient form of one of `which is a strong barrel, D. Through the head of this barrel are inserted two metallic pipes, b and', projecting a short distance above and below said heads,

with the upper ends threaded. A flexible,V pipe, E, provided with a suitable metallic mouthlpiece, c, and attached by a convenient swivel-coupling to the pipe b, is of suliicient length to reach into the vault or receptacle F intended to be emptied. Another iiexible pipe, G, attached iu the same manner to the pipe b', extends into the air-pump. A third ilexible pipe, G', extends from the air-pump to a metallic tube, extending from the bottom on one side of the deodorizer ll. This flexible pipe should be of suflicient length to be placed in the room where the vault to be cleaned is placed.

The deodorizer is a metallic vessel, eonveu iently cdindrical, divided by several perforated diaphragms, e, and should have a'eover to close it tightly, and a bail by which it may be carried. In this deodorizer, before it is put in use,there is placed chloride of lime, 0r manganese, or other suitable disinfectant, or chlorine, generated in the various ways upon one or more of the diaphragms In order to ascertain when the-tank or reeeptacle D is suiciently iilled, there may be placed in its head an ordinary iioat,iwith its stem projecting through the' head, or the ort dinarymiode of striki ngrupon the 'tank troni' time to time may be used, in which mode the progress of the filling may be determined from..

. the sound.

In the use of my apparatus, the pipe E, with its metallic end, being. inserted in the vault to be. cleaned, the pump is started, and thereby a vacuum created in the tank D, the' effect of which is to draw'up the' contents of the vault into said tank..

The air drawn into the pump, which is very offensive inodor, passes from the -tank D into the pump, through the tube G into the pump, and is expelled from the pump through the tube G into the deodorizer H, where the air, passing through the disinfectants, becomes deodorized.

By placing the deodorizer in the'room Where the vault is, all unpleasant smell arising from.

said vault is prevented by the proximity of the deodorizer, and the process of cleaning the vault becomes inol'ensive.

0f course, as soon as one' tank, l), is filled,`f

another similar one is substituted in itsplace, and when all are illed they may be emptied in any convenient way..

llavin g thus described my apparatus, what I claim as new therein and my invention is,-

natiou ot' the vessel l), flexible pipes from the vault t0 the upper part of the tank, and from the upper part of the tank to the air-pump, and au air-pump, whereby vessel and pump are independent-ly movable about the vault.

2. The tank l), the ai1-pump,and the dei 1. In a vault-cleaning apparatus, the combiodorizer'H, the several parts being connected odorizer containining chlorine or chlorides, by the exible pipes F, G, and G', whereby` substantially as described.v I the noisome air is drawn from the tank, passed This specification si gncd and witnessed this through the air-pump, and deodorized, sub- 23d day of November, 1874.

'stantially as described and shown.

3. The process described, wherein thewnoi` some air drawn from a vault, in the act of Witnesses:-

' cleaning it, is taken into a tank, thence into l G. L. DYEB,
